Auditing impact on database resources

Auditing has the potential to be extremely resource-intensive. A new record is written to the _aud-data table every time an event occurs. An additional record or records is written to the _aud-data-value table every time an audited field data change event occurs. Depending on the level of auditing specified, you could be storing both the original and the changed values of a field every time it is updated.
